Congratulations on recent updates!
This is the thread's initial revision.
It's rather hard to improve even a tiny at the top, and now I see Knight ascended to #6 with noticeable APS gain after a few versions, congratulations!
I also came back to ScalarBot and decided now to do what I really want to do. I found myself changing things I don't want to change and ended up losing points, so now I switched to focus on what I want to do the most, and gained noticeable improvement, e.g. ScalarBot 2.8 wins around 60% constantly against 2.7.101. I think the most important part about this game is not about tweaking style only tiny things, rather, aggressive changes that gets the point gives you the most gains. Yes, tiny things are still important, but I think you can lose score easily by making mistake in it, but you can never earn a tiny from that.
Btw, I'm really interested in the recent changes of Knight ;) Well you add that at some point?
